Hi Guys,

Many thanks for all the responses. I think JohnDThompson and others are spot on, in that this is just a cheap bike, so some parts are not designed to be serviced - the bike this hub is on is a Viking Road FX...and this is a cheap bike...but not a "bad" bike.

So basically just undo the locking nut on the fixed gear side, and see if I can slide the whole assembly out with both the fixed gear, and free hub still in place on the wheel? The fixed gear looks like it is notched for a puller, but would there be any reason for me to remove the fixed gear first?
